Scrapebox Changed Config Automatically?

I've only been using SB for about a month, but I noticed yesterday my config was all messed up. My Google/Bing/Yahoo harvester settings were all set to 10, and what's weird is that I couldn't change them. I can usually slide them to the right to increase them, but this option wasn't available for some reason. Some of the other settings were 'not default' as well, such as maxed 100 ping websites (which I never mess with). I could change all of the other settings but not the harvester. Also noticed the use blacklist option was turned off....

I fixed this problem by replacing the config folder of my SB with a new fresh config folder, but I'm wondering what caused this in the first place. Is my VPS hacked? Is it a bug?
